More about the endangered Blanding’s Turtles of Ontario

blandings2Blanding’s Turtle –  Scientific name: Emydoidea blandingii
Status: Threatened
“Threatened” means the species lives in the wild in Ontario, is not endangered, but is likely to become endangered if steps are not taken to address factors threatening it.

The Blanding’s Turtle was already assessed as threatened when the Endangered Species Act took effect in 2008.

What it looks like:
The Blanding’s Turtle is a medium-sized turtle easily identified by its bright yellow throat and chin. Unlike most Ontario turtles that have wide, flatter shells, the Blanding’s Turtle has a domed shell that resembles an army helmet. Its shell is black to brown with yellow flecks and streaks and can reach 27 centimetres long. Its head and limbs are black-grey and the bottom shell is rich yellow.blandings3

Where it lives:
Blanding’s Turtles live in shallow water, usually in large wetlands and shallow lakes with lots of water plants. t is not unusual, though, to find them hundreds of metres from the nearest water body, especially while they are searching for a mate or traveling to a nesting site. landing’s Turtles hibernate in the mud at the bottom of permanent water bodies from late October until the end of April.

Where it’s been found in Ontario:
The Blanding’s Turtle is found in and around the Great Lakes Basin, with isolated populations elsewhere in the United States and Canada.

In Canada, the Blanding’s Turtle is separated into the Great Lakes-St. Lawrence population and the Nova Scotia population.

Blanding’s Turtles can be found throughout southern, central and eastern Ontario.

What threatens it:
The most significant threats to the Blanding’s Turtle are loss or fragmenting of habitat, motor vehicles, and raccoons and foxes that prey on eggs.

Illegal collection for the pet trade is also a serious threat. Blanding’s Turtles are slow breeders – they don’t start to lay eggs until they are in their teens or twenties – so adult deaths of breeding age adults can have major impacts on the species.

Action that Ontario is  taking:
Threatened Species and their general habitat are automatically protected

Habitat protection:
General habitat descriptions are technical, science-based documents that provide greater clarity on the area of habitat protected for a species.

What you can do
Report a Sighting:
The Ministry of Natural Resources and Forestry tracks species at risk such as the Blanding’s Turtle. You can use a handy online form to report your sightings to the Natural Heritage Information Centre. Photographs with specific locations or mapping coordinates are always helpful.

Volunteer: Volunteer with your local nature club or provincial park to participate in surveys or stewardship work focused on species at risk.

Be a good steward: Private land owners have a very important role to play in species recovery. If you find Blanding’s Turtle on your land, you may be eligible for stewardship programs that support the protection and recovery of species at risk and their habitats.

As with many other rare plants and animals, the Blanding’s Turtle is at risk due to the loss of wetland habitat. You can help by protecting any wetlands and surrounding natural vegetation on your property.

Every year, turtles all over the province must cross busy roads to get to their nesting sites. Female Blanding’s Turtles sometimes mistake gravel shoulders of roads as good nesting sites! Watch for turtles on the roads, especially between May and October. Never buy native species of turtles or any turtles that have been caught in the wild. If you see native species of turtles for sale in a pet store or food market, please contact the Ministry of Natural Resources and Forestry.

The Ontario Reptile and Amphibian Atlas also collects observations of all Ontario reptiles and amphibians. Submit your observations at:

  • Quick facts: 
  • The size of the Great Lakes-St. Lawrence Blanding’s Turtle population is impossible to estimate accurately, as only limited data are available.
  • It can take a female Blanding’s Turtle up to 25 years to mature.
  • This long-lived species can survive in the wild for more than 75 years.
  • Unlike other Ontario turtles, the bottom shell is hinged so that some Blanding’s Turtles can completely close their shell after pulling in their head and feet.
